No, if you set CURLOPT_USERPWD to an easy handle, all requests done using that
handle will send/use those credentials.

Right, but this description omits a very important detail! Your code *ALSO*
sets CURLAUTH_ANY, thus enabling all authentication methods libcurl knows

Basic credentials in requests. It would be stupid to do so.
